  1. 1 extremely funny (adj.)
    B2 Upper Intermediate

    extremely funny; something that makes you laugh out loud.

    extremely amusing or funny; as an extreme adjective, it is typically modified by 'absolutely' rather than 'very'.

    Example

    The comedian told a hilarious story about his first day at work.

    Example

    The play was absolutely hilarious, with the audience frequently erupting into spontaneous laughter at the lead actor's physical comedy.

    Usage

    Usually functions as a non-gradable adjective; it is more common in spoken English and informal writing than in academic contexts.

    Teacher's tip

    Learners often over-use 'very' with this word; remind them that 'hilarious' is already at the top of the 'funny' scale.

    Pitfall
    The movie was very hilarious.
    The movie was absolutely hilarious.

    Since 'hilarious' already means 'very funny', you should use 'absolutely' or 'really' instead of 'very' to add emphasis.

Origin

Learned borrowing from Latin hilaris (“cheerful”) + -ous, from Ancient Greek ἱλαρός (hilarós, “cheerful, merry”).
